It's more common than you think.
Almost all gas engines are now direct injected. The conversion started as early as 2002 - some manufacturers waited until 2010-2015 to make the switch. With this has come a new problem of carbon buildup. Previously engines were port injected. This prevented carbon build up because when the fuel was injected it was into the intake port and that allowed the fuel to pass over the intake valves and kept the carbon build up to a minimum.
New direct injection engines bypasses the intake port and the fuel is sprayed directly into the cylinder. This allows for fuel to be more regulated into the cylinder and more precise timing. The trade off is carbon buildup on the intake valves.
We do have a way to help prevent carbon buildup on your engine. An induction service performed every 15,000 miles can help prevent carbon from building up on the intake valves. This service is only recommended to those who have lower mileage or new engines. If we were to perform this service on an already carboned engine then a piece of carbon could break off and cause engine damage.
